Genes affected
DZANK1 (HGNC:15858): (double zinc ribbon and ankyrin repeat domains 1) This gene contains two ankyrin repeat-encoding regions. Ankyrin repeats are tandemly repeated modules of about 33 amino acids described as L-shaped structures consisting of a beta-hairpin and two alpha-helices. Ankyrin repeats occur in a large number of functionally diverse proteins, mainly from eukaryotes, and are known to function as protein-protein interaction domains. [provided by RefSeq, Dec 2018]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 28, 2023The c.962G>C (p.C321S) alteration is located in exon 11 (coding exon 10) of the DZANK1 gene. This alteration results from a G to C substitution at nucleotide position 962, causing the cysteine (C) at amino acid position 321 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
